One item of note is how to rein­stall your iLife appli­ca­tions after a restore of Lion. You can just down­load them from the Mac App Store if Lion came pre-​​installed on your Mac. Here’s how:

After instal­la­tion, start from Lion.

Double-​​click the App Store icon in the dock.

Enter your Apple ID and password.

Click Pur­chases.

If you haven’t pre­vi­ously accepted your bun­dled iLife appli­ca­tions within the Mac App Store, you should see your iLife appli­ca­tions appear in the Accept por­tion of the screen. Click Accept.

You may be asked for your Apple ID and pass­word once again. Your iLife appli­ca­tions now move to the Pur­chased sec­tion. These appli­ca­tions are part of the soft­ware that came with your Lion based com­puter. Your account will not be charged for them. Click Install to com­pete instal­la­tion of your applications.

Slick. No more wor­ry­ing about where your iLife disc is in some drawer you haven’t cleaned out in years.
